| * | hwmon: (coretemp) Extend the bitmask to read temperature to 0xffRicardo Neri2024-04-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Intel Software Development manual defines the temperature digital readout as the bits [22:16] of the IA32_[PACKAGE]_THERM_STATUS registers. Bit 23 is specified as reserved. In recent processors, however, the temperature digital readout uses bits [23:16]. In those processors, using the bitmask 0x7f would lead to incorrect readings if the temperature deviates from TjMax by more than 127 degrees Celsius. Although not guaranteed, bit 23 is likely to be 0 in processors from a few generations ago. The temperature reading would still be correct in those processors when using a 0xff bitmask. Model-specific provisions can be made for older processors in which bit 23 is not 0 should the need arise.

| * | hwmon: (aspeed-g6-pwm-tach) Convert to platform remove callback returning voidUwe Kleine-König2024-04-281-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() is renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver support two functions: PWM and Tachometer. The PWM feature can handle up to 16 output ports, while the Tachometer can monitor to up to 16 input ports as well. This driver implements them by exposing two kernel subsystems: PWM and HWMON. The PWM subsystem can be utilized alongside existing drivers for controlling elements such as fans (pwm-fan.c), beepers (pwm-beeper.c) and so on. Through the HWMON subsystem, the driver provides sysfs interfaces for fan.

The current implementation would try to register the second interrupt even if the first one failed, which is unnecessary. Moreover, if no irqs are available, the return value should be zero (the driver supports the use case with no interrupts). Currently the initial value is unassigned and that may lead to returning an unknown value if stack variables are not automatically set to zero and no irqs were provided.
